RIP400 shown in Fig. 2 has input configuration file 610, output profiles 620 and color libraries 640.Input Configuration file 610 is the file described to the color characteristics of the ink used in target print machine 300.Output is matched Setting file 620 is the file described to the color characteristics of the ink used in ink-jet printer 200.Match about two File 610,620 is set, for example, being able to use the data format of ICC Profile.The processing color of printed original data D0 CMYK_inThe color Lab of Lab color space is converted into according to the A2B table of input configuration file 610_S1, and matched according to output It sets the B2A table 621 (example of the first conversion table) of file 620 and is converted into print color cmyk_p.It is used in printer 200 In the case where the ink of four color of total of CMYK, print color cmyk_pIt is exported to printer 200, and is reproduced in printed article On.Following situation is shown in FIG. 2, that is, printer 200 prints the ratio for indicating print color cmykp in printed object Each colour code that colour chart and color measuring device 120 compare colour chart CH1 carries out colour examining to obtain measured color value Lab_pThe case where.It is beating In the case that print machine 200 also uses the ink of Lc (pale bluish green), Lm (shallow magenta), Dy (buff), Lk (light/dark balance) etc., When print color cmykp points are dark and light by RIP400 or printer 200, printer 200 can be by print color Cmykp is reproduced on printed article.Certainly, print color itself is not defined to four color of total of CMYK yet.

In addition, RIP400 can be referring to color libraries 640 in the case where setting color designation in printed original data D0 And color designation is converted to the color Lab of Lab color space_S1。

Also, RIP400 also has following input configuration file, which is used in addition to processing color CMYK_inAlso the processing color of the usage amount of the color material for the three primary colors CMY for indicating only to become subtractive color mixture (is set as in addition CMY_in), indicate that the processing color for becoming the intensity of the three primary colors R (red) of addition colour mixture, G (green) and B (blue) (is set as RGB_in) etc. and the coordinate value of Lab color space converted.Therefore, RIP400 also can be by processing color CMYin, processing color Color RGBin etc. is converted to print color cmykp via Lab color space.Moreover, RIP400 can also input Lab color sky Between color Lab_S1And be converted to print color cmyk_p。

According to the above aspect, the face close with the color of target print machine 300 can be reproduced by ink-jet printer 200 Color.But in fact, sometimes due to variation of the error of configuration file, colour examining error, printer etc. and can not reproduce and be expected Color.In this case, by being modified to configuration file 610,620, the conversion accuracy of Lai Tigao object color. In the case where being modified to output profiles 620, it may be considered that by the Lab in PCS (configuration file connection space)_S1Value As target value, the result (Lab of colour examining will be carried out to the color printed in printer 200_p) it is used as current value, and to the two Color difference calculated, and output profiles 620 are modified in a manner of making the color difference tail off.In addition, to defeated Enter in the case that configuration file 610 is modified, it may be considered that using input configuration file 610 and output profiles 620 Colour chart is converted and printed to the data of comparison colour chart, and to the colour examining result (Lab of each colour code_p) and object color component It is worth (Lab_T) color difference calculated, and in a manner of making the color difference tail off and to input configuration file 610 be modified.

But object feedback will be adjusted on the basis of the coordinate by PCS in the case where controlled plant configuration file, have When the color of printed article implemented by printer 200 (be measured color value Lab as numerical value_p) do not become be intended to adjusting knot Fruit.One of its reason is, the color being conditioned in PCS become sometimes output profiles 620 color reproduction region it Outer color, and be mapped on color reproduction region.In addition, even if the color being conditioned in PCS is located at output configuration text In the color reproduction region of part 620, the mistake for depending on the precision of B2A table 621 of output profiles 620 can be also generated sometimes Difference.Be intended to adjusted result will not be become sometimes as a result,.

In this concrete example, improved using the A2B table 622 (example of the second conversion table) of output profiles 620 The color reproduction accuracy of configuration file after adjusting.In fig. 2 it is shown that with closest following target PCS value Lab_STSide Formula makes print color cmyk_pAdjusting color-values Δ cmyk optimize the case where, target PCS value Lab_STFor from print color cmyk_pThe simulation color-values Lab of middle acquisition_S2It is upper to add regulated quantity (relative value) Δ Lab_T-pObtained from be worth.What this was optimised Color-values Δ cmyk is adjusted to be used in the adjusting of controlled plant configuration file.

After the processing of S124, host apparatus 100 implements optimization processing shown in Fig. 8.Optimization processing corresponds to In optimization process ST4, optimization function FU4 and optimization portion U4.In this concrete example, in the solution exploration processing of S210 The BFGS method (Broyden-Fletcher-Goldfarb-Shanno method) in quasi- Newton method is used.It is of course also possible to By other than BFGS method quasi- Newton method, be used in such as DFP method in the solution exploration processing of S210.In addition, in addition to quasi- Newton method In addition, additionally it is possible to which Newton method, conjugate gradient method etc. are used in the solution exploration processing of S210.

When starting optimizations shown in Fig. 8 and handling, host apparatus 100 is by the adjusting on the basis of the coordinate of PCS CS3 The relative value Δ Lab of target T0_T-pIt is added in controlled plant PCS value Lab_S2Above to target PCS value Lab_STIt is calculated (S202)。

Lab_ST=Lab_S2+ΔLab_T-p

In next S204, host apparatus 100 sets in order to consistent with target T0 is adjusted and is added in controlled plant color Color value cmyk_pOn adjusting color-values Δ cmyk initial value Δ cmyk_i.As illustrated in Fig. 9, prepare multiple initial value Δs cmyk_i, and according to these initial value Δs cmyk_iAnd it is one by one set.Variable i herein is to know to the initial value Other variable.There may be multiple relative to three-dimensional output (Lab for the A2B table 622 for being used in the optimization processing of S210 Value) four-dimensional input (cmyk value).Accordingly, it is possible in the presence of four-dimensional adjusting color-values Δ cmyk is largely set as variable The extreme value (minimum or maximum) of objective function y=f (Δ cmyk).Therefore, according to mutually different multiple initial value Δs cmyk_iAnd implement the solution exploration processing of S210, and according to obtained optimal solution candidate Δ cmyk_pbTo obtain optimal solution Δ cmyk_b。

Fig. 9 is to schematically show the initial value Δ cmyk for making to adjust color-values Δ cmyk_iThe example of change.Here, by In cmyk color space be four-dimensional color space, therefore, in fig. 9 it is shown that the three-dimensional that is formed by c-axis and m axis and y-axis Imaginary space.In Fig. 9, the circular mark for depicting hacures indicates controlled plant color-values cmyk_pPosition.Here, with (Δ ci, Δ mi, Δ yi, Δ ki) indicates initial value Δ cmyk_iEach ingredient.One initial value Δ cmyk_iFor (Δ ci, Δ mi, Δ yi, Δ ki)=(0,0,0,0).It is denoted as Δ cmyk_i=0.In this concrete example, at the beginning of preparation 3 × 3 × 3=27 Initial value Δ cmyk_i, 3 × 3 × 3=27 initial value Δ cmyk_iWith Δ cmyk_iCentered on=0, make c value every spacing value Sc (Sc > 0) makes m value every spacing value Sm (Sm > 0), and deviates y value every spacing value Sy (Sy > 0).In order to make Processing high speed is optimized, the initial value Δ k of k is fixed as 0.Therefore, initial value Δ cmyk_iIt is as follows.

(Δ ci, Δ mi, Δ yi, Δ ki)=(+Sc ,+Sm ,+Sy, 0)

(Δ ci, Δ mi, Δ yi, Δ ki)=(+Sc ,+Sm, 0,0)

(Δ ci, Δ mi, Δ yi, Δ ki)=(+Sc ,+Sm ,-Sy, 0)

(Δ ci, Δ mi, Δ yi, Δ ki)=(+Sc, 0 ,+Sy, 0)

(Δ ci, Δ mi, Δ yi, Δ ki)=(+Sc, 0,0,0)

…

(Δ ci, Δ mi, Δ yi, Δ ki)=(0,0,0,0)

…

(Δ ci, Δ mi, Δ yi, Δ ki)=(- Sc ,-Sm ,-Sy, 0)

Certainly, the initial value Δ k of k can also be deviated every spacing value Sk (Sk > 0).

Also, the obtaining as the c value of the second coordinate value, m value, y value and k value in cmyk color space (CS2) Range be not defined, but can be set to 0~100 (0≤c≤100,0≤m≤100,0≤y≤100 and 0≤k≤ 100).It is set as in cmyk color space (CS2), the coordinate of the mesh point GD3 of A2B table 622 (referring to Fig. 5) and initial Tentative color-values cmyk_pp=cmyk_p+Δcmyk_iCoordinate be identical standard.Initial value Δ cmyk_iSpacing value Sc, Sm, Sy Such as can be set to the interval Gc of mesh point GD3,0.5~2 times or so of Gm, Gy.It is expressed as follows with formula.

0.5×Gc≤Sc≤2×Gc

0.5×Gm≤Sm≤2×Gm

0.5×Gy≤Sy≤2×Gy

In the case where the initial value Δ k of k also sets multiple, the spacing value of initial value Δ k (is set as Sk.) for example can also be with The interval for the mesh point GD3 being set as in k axis direction (is set as Gk.) 0.5~2 times or so.

0.5×Gk≤Sk≤2×Gk

As the interval Gc, Gm, Gy that spacing value Sc, Sm, Sy, Sk are set as to mesh point GD3, at 0.5~2 times or so of Gk, Optimal solution Δ cmyk can be effectively determined_b。

In setting initial value Δ cmyk_iLater, host apparatus 100 implements solution exploration processing (S210).At the solution exploration In reason, the processing of S212~S224 is repeated.

Firstly, host apparatus 100 is in controlled plant color-values cmyk in S212_pUpper add adjusts color-values Δ The tentative color-values cmyk obtained after cmyk_ppIt is calculated.The adjusting color-values Δ cmyk when processing of S212 is carried out at first For initial value Δ cmyk_i。

In next S214, host apparatus 100 is according to A2B table 622 and by tentative color-values cmyk_ppIt is converted to tentative PCS value Lab_S3.It is expressed as follows with formula.

Lab_S3=f_icc(OutputProfile, A2B, cmyk_pp)

In next S216, host apparatus 100 is to tentative PCS value Lab_S3With target PCS value Lab_STColor difference Δ E₀₀ Square calculated.Pass through square Δ E using color difference₀₀ ², and make color difference Δ E₀₀Contained subduplicate operation disappears, from And solution is made to explore processing high speed.Square Δ E of color difference₀₀ ²It is contained in objective function y=f (Δ cmyk).Therefore, target Function y=f (Δ cmyk) includes making tentative PCS value Lab_S3Close to target PCS value Lab_ST=Lab_S2+ΔLab_T-pElement.

Also, although many times are taken since solution explores processing, it also can replace square Δ E of color difference₀₀ ², And make color difference Δ E₀₀It itself is contained in objective function y=f (Δ cmyk).Alternatively, it is also possible to replace color difference Δ E₀₀, and use Color difference Δ E^* _ab, the absolute value of the difference of L value and the absolute value of the difference of a value and the summation of absolute value of the difference of b value etc..

In next S218, host apparatus 100 is in order to calculate objective function y=f (Δ cmyk), and in color Poor Δ E₀₀Except to the vector by cmyk color space (CS2) come show adjust color-values Δ cmyk when the vector size V's square is calculated.When with (Δ c, Δ m, when Δ y, Δ k) indicate to adjust each ingredient of color-values Δ cmyk, with cmyk face The size V of the vector when vector representation of the colour space (CS2) adjusts color-values Δ cmyk becomes following formula.

V={ Δ c²+Δm²+Δy²+Δk²}^1/2

By being contained in the size V for the vector for adjusting color-values Δ cmyk in objective function y=f (Δ cmyk), from And the case where inhibiting any absolute value in the Δ c for adjusting color-values Δ cmyk, Δ m, Δ y and Δ k highlightedly to become larger.

Due to including square Δ E of color difference in objective function y=f (Δ cmyk)₀₀ ², therefore, adjust color-values Δ cmyk The size V of vector be also squared, to be contained in objective function y=f (Δ cmyk).

V²=Δ c²+Δm²+Δy²+Δk²

Subduplicate operation contained by the size V of vector disappears as a result, so that solution be made to explore processing high speed.

Although also, taken a lot of time since solution explores processing, the arrow for adjusting color-values Δ cmyk can also be replaced Square V of the size of amount², and the size V for the vector for adjusting color-values Δ cmyk is made itself to be contained in objective function y=f (Δ Cmyk in).The size V of the vector of color-values Δ cmyk is adjusted alternatively, it is also possible to replacement, and utilizes Δ c, Δ m, Δ y, Δ k each From absolute value summation etc..

In next S220, host apparatus 100 is to the obtainable model for being based on cmyk value (example of the second coordinate value) The cost C for enclosing 0~100 restriction condition is calculated.This is because tentative color-values cmyk_pp=cmyk_p+ Δ cmyk is restrained The reason of in the range of the obtainable range 0~100 of cmyk value.Here, with (c_pp, m_pp, y_pp, k_pp) indicate tentative color Value cmyk_pp.Cost C can for example be calculated according to the following formula.

c_ppWhen < 0, C=-c_pp×Cco

c_ppWhen > 100, C=(c_pp-100)×Cco

m_ppWhen < 0, C=-m_pp×Cco

m_ppWhen > 100, C=(m_pp-100)×Cco

y_ppWhen < 0, C=-y_pp×Cco

y_ppWhen > 100, C=(y_pp-100)×Cco

k_ppWhen < 0, C=-k_pp×Cco

k_ppWhen > 100, C=(k_pp-100)×Cco

In situation other than the above, C=0

But it is preferably sufficiently large compared with the obtainable range 0~100 of cmyk value that coefficient Cco, which is positive number, Number, i.e., 10³≤Cco≤10⁹Left and right.

When above-mentioned cost C is contained in objective function y=f (Δ cmyk), implement in tentative color-values cmyk_ppModel The optimization processing of the obtainable range 0~100 of cmyk value is applied in the restriction condition enclosed.

It certainly, also can be similarly even if in the case where the obtainable range of the second coordinate value is other than 0~100 Cost C is calculated.For example, being set as the second coordinate value is rgb value, obtainable range is 0~255, by tentative color-values RGB_ppIt is each at being divided into (R_pp, G_pp, B_pp).The cost C of objective function y=f (Δ RGB) for example can according to the following formula into Row calculates.

R_ppWhen < 0, C=-R_pp×Cco

R_ppWhen > 255, C=(R_pp-255)×Cco

G_ppWhen < 0, C=-G_pp×Cco

G_ppWhen > 255, C=(G_pp-255)×Cco

B_ppWhen < 0, C=-B_pp×Cco

B_ppWhen > 255, C=(B_pp-255)×Cco

In situation other than the above, C=0

Here, it is preferably sufficiently large compared with the obtainable range 0~255 of rgb value that coefficient Cco, which is positive number, Number, i.e., 10³≤Cco≤10⁹Left and right.

In addition, the element other than also may include the obtainable range of the second coordinate value in cost C.For example, right It, can also be on cost C when generating mistake in the case that some adjusts the processing that color-values Δ cmyk implements S212~S220 In addition 10³~10⁹The value of left and right is calculated.

In next S222, square Δ E of the host apparatus 100 to color difference₀₀ ², adjust color-values Δ cmyk vector Size square V²And the objective function y=f (Δ cmyk) comprising cost C is calculated.Objective function y=f (Δ Cmyk it) is for example indicated by following formula.

Y=Δ E₀₀ ²+w×V²+C

Wherein, coefficient w is positive number, in any absolute value of Δ c, Δ m, Δ y and Δ k to adjusting color-values Δ cmyk Prominent the case where becoming larger, carries out on this point of inhibiting, preferably, 1 w≤10 < or so.

The processing of above-mentioned S212~S222 is repeated, until discovery makes objective function y=f (Δ cmyk) become pole Solution (the optimal solution candidate Δ cmyk of small value_pb) until (S224).Due at first implement S224 processing in the case where can not be right Whether objective function y=f (Δ cmyk) is that minimum is judged, therefore, host apparatus 100 is changing adjusting color with small quantity On the basis of coloured silk value Δ cmyk, make that processing returns to S212.Hereafter, host apparatus 100 is changing adjusting color-values with small quantity The processing of S212~S224 is repeated while Δ cmyk.Host apparatus 100 makes objective function y=f (Δ cmyk) in discovery When solution as minimum, which is set as optimal solution candidate Δ cmyk_pb, to terminate the solution exploration processing of S210.

The processing of S204~S210 is repeated in host apparatus 100, until all setting adjusts the first of color-values Δ cmyk Initial value Δ cmyk_iUntil (S230).It is directed to each initial value Δ cmyk as a result,_iAnd find out optimal solution candidate Δ cmyk_pb。

In next S232, host apparatus 100 is according to multiple optimal solution candidate Δ cmyk_pbAnd obtain optimal solution Δ cmyk_b.In the solution exploration processing of S210, for each initial value Δ cmyk_iAnd calculate objective function y=Δ E₀₀ ²+w×V² +C.As long as example, host apparatus 100 is in S232 by each initial value Δ cmyk_iThe value of objective function y when becoming minimum Optimal solution candidate Δ cmyk_pbIt is determined as optimal solution Δ cmyk_b?.

Obtained solution Δ cmyk_bTo make tentative PCS value Lab_S3Extremely close to target PCS value Lab_ST=Lab_S2+Δ Lab_T-pOptimal solution.Obtaining optimal solution Δ cmyk_bWhen, it is suppressed that adjust Δ c, Δ m, Δ y and the Δ of color-values Δ cmyk Any absolute value in k protrudes the case where becoming larger, and fixes tentatively color-values cmyk_pp=controlled plant color-values cmyk_p+ adjust color-values Δ cmyk is limited in the obtainable range of cmyk value.By utilizing such optimal solution Δ cmyk_bAnd to controlled plant Configuration file 550 is adjusted, so as to improve the color reproduction accuracy of controlled plant configuration file.

Firstly, 6A, Figure 16 B referring to Fig.1, to adjusted in adjustable range A0 the concept of controlled plant configuration file 550 into Row explanation.Here, horizontal axis indicates the input value of some reference axis along input color space CS4 in Figure 16 A, Figure 16 B, The longitudinal axis indicates the output valve of some reference axis along output color space CS5.For example, being CMYK in input color space CS4 In the case where color space, horizontal axis becomes C axis, M axis, Y-axis or K axis.In the feelings that output color space CS5 is Lab color space Under condition, the longitudinal axis becomes L axis, a axis or b axis.White circle on horizontal axis indicates mesh point GD0.

Figure 16 A schematically illustrates the regulated quantity AD of each mesh point GD0 when output valve is adjusted.User is signified Fixed point of adjustment P0 is corresponding with input value Input_P.When user indicate regulated quantity AdjustData using as adjust target T0 When, it is set on current output valve CurrentOut_P corresponding with input value Input_P plus regulated quantity Target value TargetOut_P is adjusted obtained from AdjustData.Certainly, if controlled plant color space CS6 is Lab color Space, then current output valve CurrentOut_P and adjusting target value TargetOut_P are indicated by Lab value, regulated quantity AdjustData is indicated by the relative value (Δ Lp, Δ ap, Δ bp) of Lab value.

By the input shown in Fig. 7 for specifying column 850 or target region of acceptance 840 to adjustable range, thus in regulated quantity Adjustable range A0 is set in AdjustData.Substantially, making the regulated quantity of the output valve relative to input value Input_P becomes Maximum, to make regulated quantity become 0 on the boundary of adjustable range A0.But since actual metering needle configures controlled plant The mesh point GD0 of file 550 and be carried out, therefore, sometimes adjust will affect to compared with set adjustable range A0 and compared with Big range.

Figure 16 B is to schematically illustrate the regulated quantity AD of each mesh point GD0 when input value is adjusted.User institute Specified point of adjustment P0 is corresponding with input value Input_P.When user indicate regulated quantity AdjustData using as adjust target When T0, on input value Input_P add regulated quantity AdjustData obtained from input value Input_P+AdjustData Corresponding output valve becomes, the output valve expected at the point of adjustment P0 that user specifies.Certainly, if controlled plant color Space CS6 be Lab color space, then input value Input_P is indicated by Lab value, regulated quantity AdjustData by Lab value phase Value (Δ Lp, Δ ap, Δ bp) is indicated.

Above-mentioned modification is sat for whole reference axis of input color space CS4 and the whole of output color space CS5 Scale value and be carried out.

Next, 7A, Figure 17 B referring to Fig.1, to setting showing for regulated quantity AD in each mesh point GD0 of adjustable range A0 Example is illustrated.Here, horizontal axis indicates input value in Figure 17 A, Figure 17 B, the longitudinal axis indicates the regulated quantity AD of output valve.In addition, Triangle mark on horizontal axis indicates the mesh point (other than nearest mesh point GDnearest) for being located at adjustable range A0, horizontal Quadrangle label on axis indicates the mesh point that the output valve outside adjustable range A0 is not corrected.

Firstly, as shown in Figure 17 A, host apparatus 100 determines relative to as near adjusting each point of adjustment P0 The regulated quantity AD1 (S310 of Figure 10) of the output valve of the nearest mesh point GDnearest of the mesh point of point P0.In Figure 17 A, table Show the output valve when specifying two point of adjustment P0 (input value Input_P) in some reference axis for inputting color space CS4 Regulated quantity AD1 example.In the example of Figure 17 A, make the regulated quantity AdjustData relative to input value Input_P in original Become the regulated quantity AD1 of the output valve relative to nearest mesh point GDnearest in the state of coming.Certainly, this technology not by It is defined in the feelings for making to become regulated quantity AdjustData relative to the regulated quantity AD1 of the output valve of nearest mesh point GDnearest Condition.

Also, the nearest mesh point GDnearest for being mutually located at neighbouring multiple point of adjustment is possible to identical.In the situation Under, as long as example, at a distance from input color space CS4 until nearest mesh point GDnearest to each point of adjustment Make the regulated quantity AdjustData of each point of adjustment is average both may be used in the ratio of inverse proportion.

After the regulated quantity AD1 that the output valve relative to nearest mesh point GDnearest has been determined, as seen in this fig. 17b, Host apparatus 100 is determined relative to the mesh point (triangle being located at around nearest mesh point GDnearest in adjustable range A0 Shape label mesh point) output valve regulated quantity AD2 (S312 of Figure 10).For example, making outside relative to adjustable range A0 in advance Mesh point output valve regulated quantity become 0, by making the output valve relative to above-mentioned each nearest mesh point GDnearest Regulated quantity AD1 become AdjustData, and implement the interpolation operation realized by three-dimensional or four-dimensional 3 spline functions, from And it can determine the regulated quantity AD2 of the output valve of mesh point relative to surrounding.Here, being CMYK in input color space CS4 In the case where color space, implement the interpolation operation by 3 times four-dimensional spline functions, in input color space In the case that CS4 is Lab color space, implement the interpolation operation by 3 times three-dimensional spline functions.Pass through implementation Such interpolation operation, so that the regulated quantity AD2 of the output valve of the mesh point relative to surrounding is relative to each nearest grid The regulated quantity " 0 " of the regulated quantity AD1 of the output valve of point GDnearest and the output valve relative to the mesh point outside adjustable range A0 Between be smoothly connected.

Certainly, the case where this technology is not limited in interpolation operation using spline function.

Also, since the object of regulated quantity AD is mesh point, in the case where multiple point of adjustment are located at nearby, When carrying out color conversion to the input color of these point of adjustment according to controlled plant configuration file 550, sometimes referring to identical Mesh point.In such mesh point, the regulated quantity AdjustData of each point of adjustment is averaged to be conditioned.

After the regulated quantity AD of output valve of each mesh point relative to adjustable range A0 has been determined, host apparatus Identified regulated quantity AD is reflected in controlled plant configuration file 550 (S314 of Figure 10) by 100.That is, only need to be for adjusting Each mesh point of range A0, and obtained value is as updated after increasing regulated quantity AD in current output valve Output valve and be written into controlled plant configuration file 550.For example, if the output face of controlled plant configuration file 550 Colour space CS5 is cmyk color space, then increases regulated quantity in current output valve (being set as cq, mq, yq, kq) and (be set as Δ cq, Δ mq, Δ yq, Δ kq) obtained from value (cq+ Δ cq, mq+ Δ mq, yq+ Δ yq, kq+ Δ kq) become it is updated defeated It is worth out.Variable q herein is the variable identified to the mesh point in adjustable range A0.
